Abstract in another language
Langmuir-Hinselwood (LH) and power rate equations were applied to describe the kinetics of the Fischer-Tropsch reaction on cobalt catalysts and manganese-doped cobalt catalysts supported on carbon nanotubes (CNTs). LH-based kinetics characterize the activity behavior of the unpromoted Co/CNT system satisfactorily, but fail with respect to the manganese-promoted Co/CNT catalyst. An alternative LH equation is able to fit the experimental data, but the fitting parameters are out of the range of usual values and underrate the activity at ambient pressure regardless of manganese promotion. Application of power law rate expressions results in satisfying characterization of the kinetics in the whole CO pressure range in the promoted case and within a defined range of CO pressure in the unpromoted case.
